DEVICE FOR HOLDING A HOGS SNOUT AND SEVERING THE TENDON THEREON.

SPECIFICATION forming part of Letters Patent No. 422,041, dated February25, 1890.

Application filed October 17, 1889. Serial No. 327,335. (No model.)

ToaZZ whom it may concern:

Be it known that I, HARVEY HAMMOND SILSBY, a citizen of the UnitedStates, residing at La Oygne, in the county of Linn and State of Kansas,have invented a new and useful Holder and Cutter for Hogs. Snouts, ofwhich the following is a specification.

This invention has relation to a device for holding a hogs snout andsevering the tendons therein, whereby the hog is prevented from rooting.

Among the objects in view are to provide a clamp adapted to grip thenose and a cutter mounted on the clamp and adapted to be operated forremoving a section of the ten dons, whereby the same are prevented fromagain growing together and the rooting propensities of the hog destroyedWith these general objects in view the invention consists in a pair ofpivoted jaws terminating in rear of their pivot in handles, a movableknife mounted on one of the jaws, a lever for operating the knife, and astop against which the blade of the knife is adapt ed to be brought,Referring to the drawings, Figure 1 is a perspective of a toolconstructed in accordance with my invention, Fig. 2 is a detail of thereciprocating cutter or knife and its actuating-lever and adjustablesupport. Fig. 3 is a modification. Fig. 4: is afurther modification,

Like numerals of reference indicate like parts in all the figures of thedrawings.

In practicing my invention I provide two sections 1 of similarconstruction, and pivot the same by a bolt 2, the sections being ex,tended in rear of their pivots to form gripping-handles 3, and in frontof their pivots curved to form a pair of jaws 5, the inner faces ofwhich are of a contour adapting them to embrace the snout of a hog.

6 represents a bracket secured to the upper surface and at about thecenter of the upper jaw, the end of the bracket extending from the faceor side of the jaw to form a bearing 7, in which is mounted forreciprocation a sliding knife 8, of a width less than the depth of thehearing A perforation 9 is formed in the bracket opposite the bearing,and in the same is seated a set-screw 10, the lower end of which. bearsupon a bearingplate 11, inserted between the end of the set screw andthe upper edge of or back of the knife. i or 12 represents a knifeoperating lever, and the same is pivoted by a bolt 13 to the handle ofthe section upon the jaw of which is located a knife, the free end ofthe lever being pivotally connected, as at 14, to the rear end or shankof the knife.

15 represents a stop-block, which projects down the side of the jaw uponwhich the knife is located and into the path of theknife. The block isprovided with a shank 16,terminating in a plate 17, through which isinserted one or more screws 18, serving to secure the block upon thejaw. The knife is recessed longitudinally at its cutting end, as at 20,forming opposite side blades 21 and a central blade 22, projectingslightly beyond the side blades and under the lower end of the block,which block has its lower end beveled to form a cutting-edge 23.

Referring to Fig. 3, which is a modification of my invention, it will beseen that I employ substantially the same form and construction ofknife-block, with the exception that i the same islongitudinallyadjustable, which I accomplish by slotting thesecuring-plate, and through the slot is passed a set-screw. Inthis'instance-I employ a flat spring 24 upon the outer face of the jaw,the spring being secured to said jaw at its rear end by a screw 25, thetendency of the spring being to diverge from the jaw. An opening 26 isformed between the jaws, and in the same is pivoted anupwardly-projecting screw 27, the same passing through an opening 28,formed in the spring, and through a plate 29, having an opening 30,registering with the opening 2 and upon the screw is threaded a nut 30.The plate is provided with a bearing-stud 31 at one side, which projectsbeyond the side of the jaw, and upon the same is pivoted the knife 32,the same being extended above its pivot to form a handle 33, and havingthe same form of cutting-edge as before described with relation to thereciprocating knife, By this construction it is apparent that thebearing of the knife may be raised and lowered by means of theset-screw, and the knife therefore maintained in proper adjustment withthe knifc plate.

The manner of using my invention, and as described in the firstinstance, is as follows: The snout of a hog is gripped by the jaws,which are closed thereupon firmly, the recip- 5 rocating knife-operatinglever being swung toward the jaws. As the jaws are closed it Will beapparent that the knife-block and pointed end of the knife will sinkinto the flesh of the nose and at each side of one of the tendons, whenit simply remains to reverse the knife-operating lever, which throws theknife against the block, and thus severs and removes a section of thetendon of such a length as to prevent the possibility of the same everreuniting, and the snout of the hog is forever disabled from rooting.After one tendon has been cut the device is moved a little farther, soas to close the knives upon the next tendon, and the operation isrepeated.

In the modified construction the operation is the same, and need not bespecifically described.

In Fig. 4: I have illustrated a simplified construction that may besubstituted for the one described. This modification consists in acurved sheet-metal plate 35, the rear end of which is bolted to the jawsby their pivotbolt 2. An arm or lip 36 is formed integral with the upperedge of the same, which lip overlaps and embraces the upper edge of oneof the jaws and is provided with a set-screw37, by which it may beadjusted. In this modification I omit the separate stop-block by formingthe same integral with and striking it up from the curved plate, as at38. I also form integral with the plate a lip 39, which I bend over uponthe plate to form a keeper 40 for the reception of the sliding knife.

By the above construction it will be apparent that the knife andstop-block against which it operates can be uniformly and simultaneouslyadjusted by the same screw.

Having described my invention, what I claim is,

1. In a tool of the class described, the combination, with a pair ofsnoutinclosing jaws, of a movable knife mounted on one of the jaws andprojected beyond its inner face, said knife terminating in acutting-head having opposite cutting-edges connected at their loweredges by a transverse cutting-edge, substantially as specified.

2. The combination, with a pair of pivoted jaws adapted to inclose snoutand terminating in handles, of a stop secured to one of the jaws andterminating in a cutting-edge occurring below the inner edge of the jaw,and a movable knife mounted on one of the jaws 60 and having its bladeextending beyond the inner face of the same and adapted to come intocontact with the stop, and a pivoted lever for operating said knife,substantially as specified.

3. In a tool of the class described, the combination, with the oppositesnout-embracing curved pivoted jaws terminating in rear of their pivotsin jaw-operating handles, of a knife-block adj ustably secured to andprojecting beyond the inner face of the jaw and having its outer endsharpened, and a reciprocating knife mounted on one side of the jaw andprojecting below the same and adapted to be brought against the block,and a pivoted lever having one end connected with the knife,substantially as specified.

4. In a tool of the class described, the combination, with the pivotedjaws, of a knifeblock secured to the outside of and projecting beyondthe inner face of one of said jaws and having its end beveled to form acutting-edge,anda reciprocating knife formed of opposite blades andalowerinclined blade, and a pivoted lever-connected at one end with theknife and adapted to reciprocate the same against the block,substantially as specified.

5. In a tool of the class described, the combination, with the jaw, of abracket secured thereto, a reciprocating knife mounted in the bracket,means for adjusting the bracket, a knife-block arranged in front of theknife, and a lever for operating the knife against the block,substantially as specified.

6. The combination, with the jaws, of a bracket mounted on one of thesame and proj ected at one side beyond the jaw to form a bearing, areciprocating knife mounted in the lower end of. the bearing, abearing-plate mounted on the knife,a screw inserted through the bracketand bearing on the plate, a knifeblock arranged in the path of theknife, and

a pivoted lever for operating the knife in its bearing, substantially asspecified.
